ONLY one member of the mob that attacked Charles and Camilla’s car during the student fees riots has been brought to justice.

Scotland Yard promised a “full and thorough” investigation into the incident, yet nine months later not one of the other yobs has been identified.

Despite releasing CCTV footage of those involved and appealing to the public for information, police have made no further arrests because of “identification issues”.

The only protester to be prosecuted for the attack is 21-year-old Charlie Gilmour, even though he did not come into direct contact with the royal Rolls-Royce.

The son of Pink Floyd guitarist David Gilmour was jailed for 16 months in July for throwing a bin at Charles and Camilla’s convoy, sitting on a protection officer’s car and smashing a shop window.

A police source said: “A lot of the rioters were wearing balaclavas, masks and scarves over their faces. There were more people involved than Gilmour but he’s the only one who has been brought to court.”

Camilla could be heard screaming as she gripped Charles’s hand

The car was kicked, rocked and hit with paint bombs by up to 15 demonstrators as it made its way to the Royal Variety Performance at the London Palladium on December 9.

Prince Charles was furious and Camilla terrified by what has been described as the worst royal security blunder in a generation. The couple were left shaken as the mob chanted “Off with their heads!” and “Tory scum”. Camilla could be heard screaming as she gripped Charles’s hand. Terrified for her safety, she then dived to the floor of the car.

Although Gilmour, who was also photographed hanging from the union flag on the Cenotaph, threw a bin in the path of the convoy, he did not go as far as fellow protesters who attacked the car with their fists, boots and bottles. There were even reports Camilla had been poked with a stick. Dai Davies, former head of royal protection, said it was “extraordinary” that no more arrests had been made.

“That area is covered by good CCTV,” he said. “Even if these rioters had their faces covered it is still possible to find out who they are by looking at their clothes and studying CCTV footage from other areas such as railway stations where they may not have had their faces covered.

“The Met still hasn’t explained how and why it happened. Questions were asked at the time but no answers have been forthcoming.”

Sir Paul Stephenson, then Metropolitan Police commissioner, insisted proper procedure was followed after Charles’s protection officers were criticised for not using an alternative route to avoid the clashes.

He hailed the “enormous restraint” of the team guarding the royal couple and implied the rioters were lucky not to have been shot. He is also understood to have apologised personally to the Prince.

Clarence House refused to comment on the lack of arrests, saying: “It is entirely a police matter.”
